Ballotpedia identified 206 counties that voted for Donald Trump (R) in 2016 after voting for Barack Obama (D) in 2008 and 2012.[1] These counties are sometimes referred to as swing counties by media and political observers. Collectively, Trump won these counties by more than 580,000 votes and had an average margin of victory of 11.45 percent. The political shift in these counties was expected to have an impact on the 2018 congressional elections.

Ballotpedia compared the states featuring a 2018 Senate election with those that contained Pivot Counties. Using that information, we were able to explore which Senate races were expected to be contentious in 2018. We also compared county maps with congressional district maps to identify which congressional district the Pivot Counties were contained in. In total, the counties fell into 99 congressional districts. This includes districts that intersected with only small portions of a county as well as districts that overlapped with multiple counties. We then examined what happened in the past three congressional elections in the districts featuring these Pivot Counties and used that information to determine if the congressional districts trended in the same way. We then used those trends to highlight 2018 congressional races to watch.

Ballotpedia also analyzed data on which congressional districts experienced the sharpest drops in Democratic vote totals from 2012 to 2016. Excluding special cases in which one party was unopposed on the ballot and districts that underwent redistricting after 2012, there were 32 districts that saw a loss of at least 15 percent of Democratic votes cast from 2012 to 2016. Of those 32 districts, 18 (56%) contained one or more Pivot Counties.

HIGHLIGHTS
  • There were 19 states with a Democratic or independent incumbent senator up for re-election in 2018 that contained at least one Pivot County. Many of these states were expected to be among the most vulnerable Senate seats in the 2018 election.
  • As of the 2018 elections, the 206 Pivot Counties fell into 99 congressional districts (22.8% of districts). Of those districts, 63 (64%) were held by a Republican incumbent, while the remaining 36 (36%) had a Democratic incumbent.
  • No districts containing Pivot Counties flipped from Democratic to Republican hands in 2016, while one flipped from Republican to Democratic. However, six districts did flip from Democratic to Republican in 2014 and stayed in Republican control in 2016.
  • Note: The districts listed on this page in Pennsylvania have changed as a result of redistricting that occurred in 2018. There are now four districts in Pennsylvania that intersected with a pivot county as of November 2018: the 7th, 8th, 9th, and 16th districts.

    Senate

    The map below shows which states that had a 2018 Senate election contained Pivot Counties. Mouse over each state for more details.

    The 206 Pivot Counties fall within 34 states. Of those 34 states, 19 featured a Democratic or independent senator up for re-election in 2018. The Midwest is the region with by far the greatest concentration of these counties. Over half of the 206 counties fell within six Midwestern states: Iowa, Wisconsin, Minnesota, Michigan, Illinois, and Ohio. Of those six, Wisconsin, Minnesota, Michigan, and Ohio all featured a Democratic senator up for re-election in 2018. Those senators are Tammy Baldwin (WI), Amy Klobuchar (MN), Debbie Stabenow (MI), and Sherrod Brown (OH). These states were expected to be among the 2018 Senate battleground races.

    Other states with at least one Pivot County with a vulnerable Democratic senator in 2018 included Florida, Indiana, Maine, Montana, Pennsylvania, and Virginia. There was only one state with a Republican senator up for re-election in 2018 that was won by Hillary Clinton in 2016: Nevada, which is currently held by Sen. Dean Heller. Nevada was expected to be the most vulnerable Republican Senate seat in 2018.

    The full breakdown of the Pivot Counties by state can be seen below.

    Democratic U.S. House candidates won 113 (55 percent) of the pivot counties in 2018. Republican candidates won the other 93. In 184 pivot counties, the Republican U.S. House candidate had either a lesser margin of victory than Trump did in 2016 or lost the county to the Democratic U.S. House candidate.

    U.S. House results in Congressional districts that intersect pivot counties were similar to results across the country. Across all 435 districts, Republicans lost a net of 40 of their 235 seats (17 percent). In the 99 districts that contain pivot counties, Republicans lost a net of eight of their 63 seats (13 percent).

    Twelve districts that intersected with a pivot county changed partisan hands in 2018: 10 from Republican to Democratic, and two from Democratic to Republican. Following the election, Republicans controlled 54 seats and Democrats controlled 44 seats, for a net change of eight seats in favor of Democrats. The state board of elections did not certify results in North Carolina's 9th Congressional District.

    Districts that lost the most Democratic votes in 2016

    There were 32 congressional districts (7.4%) that saw a loss of at least 15 percent of Democratic votes cast from 2012 to 2016. This is excluding special cases in which one party was unopposed on the ballot and districts that underwent redistricting after 2012. Of those 32 districts, 18 (56%) contained one or more Pivot Counties.

    West Virginia's 3rd Congressional District experienced the sharpest loss in votes between 2012 and 2016. Incumbent Nick Rahall (D) won re-election in 2012 with 102,519 votes. Rahall was then ousted by current incumbent Evan Jenkins (R) in 2014. Jenkins went on to win re-election by a margin of 43.9 percent in 2016. The Democratic candidate in the race, Matt Detch, received just 49,708 votes, a decline of over 50 percent from 2012.

    The following table shows the full data on the districts and the votes cast for the Democratic candidate in each year.

    Margin of victory analysis

    The 206 Pivot Counties were contained within 104 congressional districts. Of those 104, 65 (63%) were held by a Republican, and the remaining 39 (38%) were held by a Democrat. When looking at those districts, we examined the margin of victory in the past three congressional elections to see if they trended in the same way as the presidential elections.

    Of the 104 congressional districts analyzed, 12 districts were in states that underwent court-ordered redistricting between the 2014 and 2016 elections (FL, NC, or VA), so they were not used when analyzing trends. This is due to the fact that the boundaries of many congressional districts in those states were altered in the process. Of the remaining 92, 77 districts (84.6%) are solid Democratic or Republican districts. The remaining 14 districts were expected to be among the more competitive U.S. House races in 2018. Five districts featured a Republican incumbent in a lean Republican district, two featured a Democratic incumbent in a lean Democratic district, and seven featured a Democratic incumbent in a district that trended more and more Republican from 2012 to 2016. A designation of lean Republican or Democratic district indicates that the average margin of victory over the years was less than ten percent.

    The remaining district was the only district of the 105 districts featuring Pivot Counties to flip in 2016, New Hampshire's 1st Congressional District. New Hampshire's 1st flipped from Republican to Democratic in 2016 and was also the only district to flip every year. The seat went back and forth between Carol Shea-Porter (D) and Frank Guinta (R) from 2010 to 2016. However, six districts flipped from Democratic to Republican in 2014 and remained in Republican hands following the 2016 elections. Comparatively, Democrats picked up six total seats in 2016, and Republicans picked up 13 total seats in 2014.

    Full margin of victory data for each congressional district containing at least one pivot county can be found in the table below.

    The district profiles in the below table can have the following designations:

    • Solid D/R - The district is a safe district for the party and generally featured margins of victory of greater than 20 percent.
    • Lean D/R - The district leans one way but is more likely to shift than a solid district and generally featured margins of victory of less than 10 percent.
    • D Trending R/R Trending D - The district is held by one party but has trended toward the other party in the past two election cycles.
    • Former D/R - The district has flipped party control since 2012.
    • Redistricting - The district has undergone redistricting since 2012 and was not used when determining trends.
